LOCK.

To all fr0/0m t may concern:

lle it known that l, Geenen lil. GAUNT, a citizen ot the United States, residing at Govington, in the county of lhenton and State oil' lentucky, have invented a new and useful lniprovement in Locks, of which the Ltollowing is a specification.

lily invention is an innn'ovement in locks and has for its object, the provision oit a simple, inexpensive device ot the character specicd, having a spring operated bolt, `which may be retracted manually or by a key, and which may be locked in extended or retracted position.

ln the drawings, Figure l is a side view ot the improvement, with a part ot the cover plate broken away, showing the bolt partly extended. llig. 2 is a side View, with the cover plate removed, and with the bolt fully extended. Fig. 3 is a section on the line 8-3 et Fig. 2. Fig. 4 is a perspective view, from above oit the latch lever, and Fig. 5 is a similar view o t the operating means for the latch lever.

'lhe present embodiment et the invention comprises a casing l, substantially rectangular in cross section and having an open side, normally closed by a cover plate 2. rlhe plate 2 is held to the casing by a screw 3, and the casing is secured in place by screws, (not shown) passing through registering openings t in the case and cover.

lhe casing is divided into two compartments by means ot a transverse partition 5, and a bolt 6 is slidable in the partit-ion and in one end et the casing. rthe outer end ot the bolt is adapted to extend through an opening 7 in the end ot the casing, and the said outer end otl the bolt is beveled or rounded on one tace, as indicated at 8.

rlhe end of the bolt, when extended beyond the casing, is adapted to engage a recess 9, in a hasp l0, which may be secured to the door casing by screws ll. The outer side l2 et the recess .is inclined, and ,the tree edge of the said side is thickened and beveled, as shown at 13 to engage the beveled tace 8 ot the bolt, to push the same inwardly, to permit the bolt to pass the said edge.

The inner end l/l of the bolt is cylindrical, while the main portion is rectangular in cross section, and the bolt is provided with oppositely extending lugs l5, l5@L at the junction ot the cylindrical portion and the main portion. ik collar 1G is secured on the inner end of the portion le et the bolt, by

Specicaton of Letters Patent.

means of a pin 17, and the said portion is slidable in an opening 18 in the partition.

A spring 19 encircles the portion llot' the bolt, between the collar 1G and the partition, and a spring 20 encircles the said portion, between the lugs l-liL and the partition. A key hole 2l is provided in the cover plate of the casing, below the belt, and an opeir ine' 29 is provided in the side of the casing in register with the circular portion et the key hole.

rthe side of the casing is longitudinally slotted., at 23, and a button or knob lis provided with a threaded stem 25, which passes through the slot, and engages an opening in the bolt. By means et the knob or button, the bolt may be retracted.

The key hole is for a key of ordii'iary construction, having a. bit for engaging the lower lug l5, to operate the bolt. llhen the key is inserted in the key hole, and turned, the bit engages lug l5, and pushes the bolt inwardly. rlhe bolt may be locked against retraction by the key, by means oli the cam. mechanism to be described. The said mechanism to be described. rllhe said mechanism comprises a cam QG, secured to a stub shaft 27, by means oft a screw 2S, a washer Q9 being arranged between the head ot the screw and the cam. The shaft has its inner end abutted against the outer tace ot the casing side, and the screuT is passed through an Opening in the wall and is engaged with the end of the shaft. The shaft has a handle 30 extending radially therefrom, outside of the casing, and by oscillating the shaft, the cam may be brought into the position of Fie. 2, to lock the bolt from inward movement, and into the position oi Fig. 1, where it will not interfere with the movement el the bolt. A latch is also provided for the bolt. The said latch comprises a lever 3l, pivoted to the casing by a screw or pin 32. The bolt is provided with a shoulder 33 facing the cam t'or engagement by lug 15a, and the end ot the lever adjacent to the lug-'l5u is normally forced downward by the free end ot a plate spring Sil, secured to the casing by a screw 35.

The opposite end of the lever Ytrom the spring 34- is provided with a pair oi longitudinally extending arms M5-$6, each of which is curved inwardly toward its :tree end, and the upper arm 36 is ot lesser length than the lower arm 36a. An operating lever 37 is pivoted in a bearing 3S on the upper end ot the case, and the said lever extends through a slot into the casing, and engages between the arms 3G-36.

The upper end of the lever is enlarged to forni an operating handle 39. Then the boltis retracted, as shown in dotted lines in F ig. l, until the lug 15l engages the shoulder 33, the spring 34 will prevent the lever lifting, and the shoulder will hold the bolt retracted.

lNhen the upper end of lever 37 is rocked toward the hasp, the lower end thereof engages and depresses the arm 3G, and lifts the opposite end of the lever and releases the lug 15a. The retraction of the bolt automatically engages lug l5a with shoulder 33. The bolt may be operated by the knob 24:, or by the key, and may be locked in closed position by the cam, and in open position by the latch.
